I don't know what you're trying to achieve or learn. I reread your initial post and if you're implying that it's possible to provide for both Cantis and caliper brakes on the same frame, yes it is. (except that you cannot provide for U-brakes (centerpull canti's) and bolt on centerpulls at the same time because of a conflict in the available real estate.

You asked a question an in good faith I tried to help you. However, I don't know how or if I can help you any more, so I'm out. As for pointing you to the literature, I'll leave you do your own research, except to suggest you start by seeking out a century old text by Archibald Sharp.
